How much ATP a person consumes...?

All well except for the begining.

Average metabolic waste is 2000 KCal, not 2000 Cal.

Sometimes dietists speak of calories meaning Kcal, just for briefing.

That's all.

It does require quite a bit of energy to break the alpha 1,4 glycosidic bond of glucose and fructose. Shouldn't that be taken into account?

Really? How much is it?

Cis or trans? That's what matters.

Well, some glycoside hydrolase would break the bond - It would probably couple ATP hydrolysis or NADH/FADH hydrolyis and use a positive magnesium ion catalyst. I'd have to find out more info and do a Gibbs on that one. I have no idea regarding the exact energy consumption. Does anyone else?

I think the professor is just looking for an estimated answer along with assumptions and calculations. I don't think he is looking for a more detailed answer involving gibbs energy and bond breaking energy since he didn't go over them in class. Thanks for the help guys
